I am posting this cause someone besides me had this problem and I hope the come back to this site and find their solution here. This was the error: I get this error 1706. No valid source could be found for product. The path c:\hp\\tmp\aio\setup\fax\Fax.msi cannot be found. Verify you have access to this location and try again or try to find the installation package "Fax.msi" in a folder from which you can install the product Fax. This is the FIX: I got this problem solved with that c:\hp\\tmp\aio\setup\fax\Fax.msi. Go to the HP site http://welcome.hp.com/country/us/en/solutions.html then type in "gr_uninst.exe" without the quotes, in the search box on the top of the page. Then click on the All-in-One Software Removal Utility (gr_uninst.exe) and download it to your desktop. Open it and it will give you two install options. I used the first option. Then after it installs there will be an icon on your desktop that says gr_uninst.exe. Just double click on it and run it. You will have to restart your computer after it is ran. After you restart your computer this problem file will reappear, but the uninstall program will want to access the internet. Let it access the internet. The problem file should dissapear after this. You are finished and it should be gone. You can delete that downloaded gr_uninst.exe file now. I'm not ignorant, I just need more learning!
